Vaidev had $52 more than Emma. After Emma spent
25 of her money, Vaidev had thrice as much money as Emma. How much money did Vaidev have at first?
| |
Vaidev |
Emma |
| Before |
9 u |
5 u |
| Change |
|
- 2 u |
| After |
9 u |
3 u |
Amount that Vaidev had in the end
= 3 x 3 u
= 9 u
If Emma had another $52 at first, the amounts that Vaidev and Emma each had at first will be the same.
9 u = 5 u + 52
9 u - 5 u = 52
4 u = 52
1 u = 52 ÷ 4 = 13
Amount Vaidev had at first
= 9 u
= 9 x 13
= $117
Answer(s): $117
